Comparing to a default value to detect if an argument was provided
forces it to at least WHNF, which can cause failure (e.g., if the
argument is a string with a quoted path from a broken package).

While we are at it I:
* Disable tests, because I can‘t keep up with the speed hls introduces
more tests that cause trouble in nixpkgs.
* Fix builds of fourmolu and retrie
* Remove the wrapper for hls which is obsolete because of improved
package detection in hie-bios. And added a note that this can be removed
for ghcide soon, too.

Rearrange the scope override of the haskell-language-server in a way
that intermediate packages don‘t cause build fails on hydra.

Increase version bounds for a hcoord dependency [0]. Also disable
checks, as upstream doesn't include the necessary files in the release
tarball [1].
